A 서버는 HP DL360 G8 / B 서버는 R620 입니다

cpupower frequency-set -g performance 로 MAX cpu 클럭에 맞추려고 하는데 두대 서버가 같은 CPU 인데 제가 뭔가 설정을 잘못했나봅니다

왜?

A 서버는 CPU max MHz: 2600.0000 밖에 안나오고 MAX는 고정되어지고 

B 서버는 CPU max MHz: 3300.0000 까지 표시되는데 MAX cpu 클럭에 맞춰지 않을까요?

서로 드라이버 정보가 다르던데 메인보드 사양 때문일 까요?

A서버 driver: pcc-cpufreq , B서버 driver: intel_pstate

 OS 는 둘다 CentOS Linux release 7.9.2009 (Core) 입니다

조언 부탁드립니다.

미리 답변에 감사드립니다.~
